I want to add an *UITapGestureRecognize*r to my UITextView, because I want to close a "Popup" where the TextView is in. So I want, that the method "hide" of the Popup class is called, when the T*extView* is tapped. I tried it like the following, but it isn't working for some reason:
UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(show)];
[gr setNumberOfTapsRequired:1];
[viewText addGestureReco开发者_JS百科gnizer:gr];
I also don't want to create a Subclass for it, because I then would need to call the "parent"-method "hide".
Maybe you now a good solution for that problem.
Thank you in advance.You shouldnt use UITapGestureRecognizer but use the UITextFieldDelegate.
You can read about it here:
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITextViewDelegate_Protocol/Reference/UITextViewDelegate.html%23//apple_ref/doc/uid/TP40006897
You basicly need to add the UITextViewDelegate to your .h file like that -
@interface MyViewController : UIViewController<UITextViewDelegate>
Then assign your controller as the delegate:
viewText.delegate =self;
Now use one of the delegation methods, maybe:
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{
// Do what you need to do...
}
Edit
Well I can think on 2 additional approaches:
- You can wrap your textView inside a UIView and add the UITapGestureRecognizer to the view.
You can use :
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:textView]; //Checks if the tap was inside the textview bounds if (CGRectContainsPoint(textView.bounds, location)){ //do something } }
Good luck
Did you try to NSLog on show method? or did you even declare and write method "show" ? It should work and that's how I did on my text view.
P.S don't forget to release your gesture instance (gr) after you add on textview :D
I had major problems getting this working also but I had one stupid problem, user interaction was turned off in the visual editor. Hope this helps someone :)
